This paper develops and implements a statistical methodology to account for the equilibrium effects (aka adverse selection) in design of risk adjustment formula in health insurance markets. Our setting is modeled on the situation in Medicare and the new state Exchanges where individuals sort...

This paper models the wage-contract negotiation procedure between a union and a firm as a sequential bargaining process in which the union also decides, in each period, whether or not to strike for the duration of that period. We show that there exist subgame-perfect equilibria in which the...

We study the question of whether there exist strategies whereby countries are able to sustain a cartel or collusive behavior when bargaining with a bank over the amount of debt to be repaid. We show that despite the existence of economies to scale in bargaining--if commitment were possible the...

Health plans paid by capitation have an incentive to distort the quality of services they offer to attract profitable and to deter unprofitable enrollees. We characterize plans' rationing as imposing a show that the profit maximizing shadow price depends on the dispersion in health costs, how...

This paper describes the role that informational imperfections in capital markets are likely to play in business cycles. It then developes a simple illustrative model of the impact of adverse selection in the equity market and the way in which this may lead to large fluctuations in the effective...

We consider a model where a worker's productivity must exceed some lower bound for himto satisfy the minimum qualifications for a particular job. If the worker's productivity exceeds some upper bound he is promoted. We assume the productivity of every worker increases with experience, tenure and...

Usinga detailed sample of semi-skilled production workers we find that holding a wide range of personal and job-related characteristics constant, workers assigned to more complex jobs seem to be more likely to quit than are workers assigned to simpler jobs. Job complexity has no discernible...

This paper presents and alternative perspective on the role of banks. We emphasize the ways in which banks act as social accountants and screening devices. In this view monetary disturbances have their effects through the disturbances which they induce in society's accounting system and in the...

We construct a model in which firms use workers' productivities in determining their job assignments. A worker's productivity must exceed some lower bound to satisfy the minimum qualifications for a particular job. If the worker's productivity exceeds some upper bound he is promoted. Under these...

Using data from the Panel Study of Income Dynamics and a proprietary sample of semi-skilled production workers, this paper investigates the reasons for the discontinuous increase in wages associated with graduation from high school. Associated with graduation from high school, we find a...
